A unique ranking of the third-party logistics companies in North America includes listings of the largest freight brokerage firms, freight forwarders, warehouse operators and dedicated contract carriage service providers.

Companies that provide same-day delivery service are seeing higher revenue, in part because of surging demand from retailers, a survey by the Messenger Courier Association of America found.

Rob Johnstone, president of the trade group based in Washington, D.C., said 58% of respondents reported that revenue was either “much better” or “better today” than it was a year ago.

“Today’s retailers want to respond quickly to changing consumer demands, while at the same time keeping their inventory costs low,” Johnstone said. “Many have the expectation that they can order inventory at the close of business and have it on-hand when they open the next day. Our industry makes that happen.”

The survey also found 63.2% of the companies cater to retailers, compared with zero who said they supported that industry just two years ago.

Other industry segments typically served by expedited delivery companies are banking, pharmaceutical, medical, third-party logistics, government and technology.

Only 10% of couriers who re-sponded to the survey said they rely solely on employee drivers. More than one-third (39%) use independent contractors to make deliveries.

“Success for those of us in this industry is heavily reliant on the ability to say ‘yes’ to our customers, no matter what or when they ask,” Johnstone said. “Over 90% of our members told us that on-demand deliveries are a critical part of their business. The use of independent contractors makes that possible.”
